Lvs-tun Demo

Lvs-tun Demo:

Test environment:

os:rhel6.4

Director:

vip:192.168.10.120

dip:192.168.10.11

rs1:rip:192.168.10.12

rs2:rip:192.168.10.13

PS: All hosts use a network card and are used Bridge network, a network card configuration multiple IP address (Lvs-tun This mode in the enterprise application of the very few, most of them use LVS-DR);

1. Configure the VIP on the director and use IPVSADM to define the Cluster service

#lsmod | grep Ipip # # # #查看内核是否加载了ipip模块

#ifconfig tunl0 up

#ifconfig eth0:0 192.168.10.120 netmask 255.255.255.255 broadcast 192.168.10.120 up

#route add-host 192.168.10.120 Dev eth0:0

#ifconfig

2. Remove all Ipvs rules and redefine the Cluster service, and set the kernel parameters

#ipvsadm-C

#ipvsadm-A-T 192.168.10.120:80-s RR

#ipvsadm-T 192.168.10.120:80-r 192.168.10.12-i

#ipvsadm-T 192.168.10.120:80-r 192.168.10.13-i

#ipvsadm-L-N

#echo "0" >/proc/sys/net/ipv4/ip_forward

#echo "1" >/proc/sys/net/ipv4/conf/all/send_redirects

#echo "1" >/proc/sys/net/ipv4/conf/default/send_redirects

#echo "1" >/proc/sys/net/ipv4/conf/eth0/send_redirects

3. Configure the Web service and VIP on the RS and set the kernel parameters

#ifconfig tunl0 192.168.10.120 netmask 255.255.255.255 broadcast 192.168.10.120 up

#route add-host 192.168.10.120 Dev tunl0

#echo "0" >/proc/sys/net/ipv4/ip_forward

#echo 1 >/proc/sys/net/ipv4/conf/tunl0/arp_ignore

#echo 2 >/proc/sys/net/ipv4/conf/tunl0/arp_announce

#echo 1 >/proc/sys/net/ipv4/conf/all/arp_ignore

#echo 2 >/proc/sys/net/ipv4/conf/all/arp_announce

#echo 0 >/proc/sys/net/ipv4/conf/tunl0/rp_filter

#echo 0 >/proc/sys/net/ipv4/conf/all/rp_filter

#yum-y Install httpd

#echo "192.168.10.12" >/var/www/html/index.html

#service httpd Start
